What should I expect in the coming days of stealing from Walgreens?

The day after stealing, I was called into work. I talked to the store manager and a consultant from a loss prevention company. I stole roughly $40 in merchandise and $60 from the cash register. I immediately payed $100 to the store and I was let go from Walgreens. A few days ago I recieved a letter from PR&A stating a settlement offer of $300. I am planning on paying it because I am 18 and I have never had any previous offenses. What should I expect after paying the settlement offer?

I would like to add that the police were not involved and the incident occurred on 1/17/13 and I received the settlement offer on 1/25/13 and no other letters concerning a court date or anything were mailed to where I live as of today. What should I expect?
